Quality control during analysis of pollutants in beer using statistical control of surrogate standard

Popis výsledku v původním jazyce

In the framework of good laboratory praxis the emphasis is placed on the quality of reproducible results. Methods of mathematic statistics are useful for this reason. In the form of regulating diagrams they can help to quick identification of the resultsoutside the required tolerances. There are a lot of various samples used for statistical regulation. One possibility how to control the efficiency of analytic process from preparing to the final determination, is using of surrogate standard. 2,4,5,6-tetrachloro -m-xylene and decachlorobiphenyl were used as surrogate standards for the determination of PCB in various types of water. These compounds were examined during relatively complicate determination of PCB in beer. The concentration was determined by Shewhart?s diagrams for individual values and sliding span according to standard ČSN ISO 8258. This example of PCB determination in beer indicates the possibility of using surrogate standards as a powerful tool for determination of qual
